Abstract
The production rate of soft real photons or soft lepton pairs by a hot QCD plasma is dominated by strong collinear divergences. As a consequence, it appears that the effective theory based on the resummation of hard thermal loops fails to handle properly these light-cone sensitive processes since some formally higher order diagrams are in reality the dominant ones.
